This method of manufacture is made up from a number of distinct steps. Rubber tube is extruded and cured on precision mandrels to fix the required internal diameter; the tube is then transferred to a grinding mandrel and the outer diameter is precision ground to the required outer diameter; the tube is then transferred to a cutting mandrel and placed in a lathe where the tube is parted off to give the required washer thickness.
Washers produced by this method do not have any flash, and the outer edge will have a ground finish. This method is not suitable for very small washer sizes; or for washers with a large face width.
We do not currently offer lathe cut washers for sale on our shop, so please contact customer services for further information.
